I have not used the machine in 3 months. I was trying help a friend out because his machine is stuck with a fan error.
Now mine just continues to say centering. I rebooted all the airport transmitters. Moved the head to the center. When it comes on, you hear the fan whirr up, then go into idle mode. then the clicking for about 15-20 seconds. Nothing moves and it sits there. -Brian
Here are a few more troubleshooting things you can try while you wait for Support to respond: https://glowforge.com/support/topic/troubleshooting/stuck-calibrating
I would bet it is the black cable at the base of the lid. I just had this same problem, and that’s what it ended up being. If you’re search for “lid cable,” you’ll probably see a lot of posts about it. Support sent me a cable, and within a few minutes, I was up and printing again.
We’re having the same problem. We repeatily are turning the GF off and on and sometimes it is working again and we can make 1 print.
We contacted support as well and they are sending us a new cable as well. Hopefully it will solve our problem.
Sadly they said we have no warranty anymore and have to pay for the cable and the shipping.
Seeing so many other users having the same problem, it seems to me it is more a design flaw then a usage issue.
I’m sorry for the trouble. I’ve checked the logs from your unit, and your Glowforge is only maintaining its connection to our servers for two or three minutes at a time before the calibration attempt times out and the unit reconnects. I can see you already emailed us about this, and we advised you to perform some Wi-Fi troubleshooting. Thanks for taking the time to try those steps out. Though network-specific Wi-Fi challenges may occur for a number of different reasons, I have a few suggestions that may help:
- If your Wi-Fi network includes several access points, it’s possible that your Glowforge needs to re-establish its connection whenever it ‘hops’ from one access point to another. As a test, you could try creating a dedicated access point for the Glowforge to see if that helps.
- Since Glowforge only uses the 2.4GHz frequency, a connection will be harder to establish and maintain on a crowded 2.4GHz network. Other devices using 2.4GHz, like cordless phones and microwaves, can cause interference and an unstable connection. You can consult your router settings to check the performance and traffic on your 2.4GHz network.
- In your network settings, check the channel you’re using for the 2.4GHz band. Trying a different channel may provide a more consistent connection.
- Though less common, DNS or name resolution conflicts may also cause intermittent connectivity problems. If you use a custom DNS configuration on your router, you might want to try default DNS settings to see if that works better.
If you’re still having trouble, there’s a test you can try that will help us narrow down the problem. If possible, could you please create a Wi-Fi hotspot with a cell phone and use that network to connect your Glowforge to Wi-Fi? This is a good way to rule out signal interference, since you can set your phone right on top of your Glowforge!
You can find instructions online to help you create a Wi-Fi hotspot using a cell phone. Make sure that you set it up to be a 2.4 GHz hotspot, since that is the frequency your Glowforge uses.
Once the Wi-Fi hotspot is broadcasting, you can connect to it by following these steps:
- Turn on your Glowforge.
- Wait 30 seconds. Then hold down the button for ten seconds until it glows teal.
- Navigate to setup.glowforge.com and follow the instructions on-screen. When prompted to connect your Glowforge to Wi-Fi, choose the hotspot you created.
- Once Wi-Fi setup is complete, go to app.glowforge.com and try a few prints.
Let us know how it goes.
